Understanding your needs when it comes to a carry-on backpack is key to choosing the right one. The Cotopaxi Allpa 35L and the Deuter Ypsilon are two worthy contenders that provide different options depending on your traveling style. The Allpa, known for its durability and impressive organizational features, boasts a laptop compartment for a 15 inch machine, a capacity of an ample 35 liters, and compatibility with 80% of airlines. With usages ranging from urban excursions to adventure travels, it indeed lives up to the praise of reviewers, one of which highlighted its intuitive internal organization as potentially the best configuration they've ever used.

On the other hand, the Deuter Ypsilon opts for a more compact design at 28 liters. It's both lighter than the Allpa, at 1.2 pounds, and smaller in size. Constructed with a durable PES 600 Coat, 600D PES, the Ypsilon presents a sturdy option for travelers who enjoy a simpler setup and folks who plan to fly with airlines that accommodate smaller carry-on luggage. However, it lacks a dedicated laptop compartment, which could be a deciding factor depending on your travel needs or preferences.

To sum up, let's list the main comparison points for both backpacks:

-   Allpa 35L: 35 liters capacity, 1.5 pounds, made of 1680D ballistic nylon paneling, laptop compartment fits a 15-inch laptop, compatible with 80% of airlines
-   Ypsilon: 28 liters capacity, 1.2 pounds, made of PES 600 Coat, 600D PES, no laptop compartment, compatible with 50% of airlines

The Allpa's advantages include a set of additional accessories that can prove quite useful for neat packers, such as a collapsible mesh laundry bag, a nylon shoe bag, and a mesh water bottle sleeve. Comfort is also a highlight with well-thought-out straps design. The rain cover is another bonus that could give relief to travelers facing unpredictable weather or rough handling.

Ultimately, choosing between the Cotopaxi Allpa 35L and the Deuter Ypsilon will come down to personal preferences and travel requirements. They both offer versatile options with differing focuses - with the Allpa veering towards the designed-for-everything route and the Ypsilon choosing to keep things minimalist and compact. So, consider your needs – size, weight, laptop compartment, airline compatibility – and pick accordingly. As the reviewers have noted – whether you are an outdoorsy traveler, a city roamer, or just someone looking for simple and durable, it is hard to go wrong with either. Cheers for your journey.
